The present application is a Continuation Application of U.S. Provisional Application Seri. No.: 14/670,357, filed Mar. 26, 2015, now U.S. Pat. No. 9,803,669, issued Oct. 31, 2017; which claims priority to U.S. Provisional Application Ser. No.: 61/971,476, filed Mar. 27, 2014; each of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present invention relates generally to a locking clip system for securing panels or other objects together, and, more particularly, to a clip system that incorporates both the male and female snapping features into each side for greater versatility and durability over conventional clip systems.

BACKGROUND

In recent years, it has become common to ship disassembled flat panel structures from factories to the user. These structures are usually broken down into components for more efficient packing and shipping. Thereafter, they are assembled on site by the user who may be unskilled at carpentry. The user may prefer that the components fit together with minimal use of tools and specialized fittings. Further, the user may wish to assemble these systems into a custom structure to better suite his/her needs. Hence it is necessary to have a clip system to allow parts to be tightly secured to one another with minimal effort and in a way that allows for more flexibility in assembling the structure.

These traditional panel systems, such as those used to assemble knock-down furniture (cabinets and shelving, closet storage, etc.), cat furniture, trade show booths, semi-permanent indoor rooms and offices, and outdoor structures such as storage sheds and temporary shelters, are generally fixed predesigned structures assembled using a variety of tools, nails, screws, bolts, and other types of fastening such as clips and adhesives for assembly.

For example, U.S. Pat. No. 8,495,997 discloses an apparatus for attaching a solar panel to a purlin. The panels are connected in a multi-step process using a variety of specialized parts. The clips and mounts allow the panels to be attached in a single arrangement. The assembly is cumbersome and the clips have no versatility. Similarly, U.S. Pat. No. 8,894,424 discloses a solar panel assembly attachment apparatus which includes several unique pieces that must be fit together in a multi-step assembly process. These current panel systems lack true modularity in that each modular component can generally only be used in one location and in one orientation within a structure.

Common assembly clips have been developed which are composed of two compatible parts that are joined together. The user joins the “female” side with a compatible “male” side, usually by snapping or bolting them together, often with the use of a tool such as a screwdriver, or wrench. By their nature, these systems limit the way in which the structure being assembled may be put together because once the “male” assembly device has been joined to the “female” assembly device, no more parts may be assembled using those assembly devices. Accordingly, traditional clip assemblies have limitations in their functionality and use and therefore, there is a need for improvements over currently available clip assemblies.

By contrast the invention herein allows for true modular and universal assemblies because each component can be used anywhere and in any orientation where they geometrically fit within a structure. Moreover the invention allows for structures which can be expanded with more components, or disassembled and rearranged into many different structures at any time.

The present invention includes a multiuse clip assembly which can be employed to firmly secure objects or assemblies to one another with minimal effort. The unique universal and expandable panel mating system does not limit the orientation, position, or number of panels that may be secured to one another. Other advantageous features of the invention will become readily apparent depending on the user's needs.

SUMMARY

The present invention recognizes that there exists a long felt need for a clip assembly that is both sturdy and user friendly for use with, among other things, furniture and other modular structures.

A first aspect of the present invention is a clip assembly in which the male and female clip features are present on each clip. Because each clip has a male and a female feature, they may be used interchangeably and one of each type of feature from each clip body will remain available to assemble more clips after two clips have been mated.

A second aspect of the present invention is a clip assembly in which the male and female mating features are preferably located on two opposing planes symmetric about the clip body such that symmetric planes form the legs of an isosceles triangle whose included angle may be any angle as required.

A third aspect of the present invention is a clip assembly in which two additional planes internal to the clip body on the female side form a load-bearing interface, wherein the planes form the legs of an isosceles triangle whose base is formed by the plane locating the female feature.

A fourth aspect of the present invention is a clip assembly that may be used when panels are to be secured perpendicular to each other such that the planes containing the male and female features are preferably at 90° to each other and each at 45° to the internal load-bearing mating planes forming a right isosceles triangle and the internal mating feature planes form the legs of a right isosceles triangle.

A fifth aspect of the present invention is a clip assembly wherein a unique universal and expandable panel mating system does not limit the orientation, position, or number of panels, wherein clips are mounted symmetrically about the panel midline in pairs, or in any even integer, but with each symmetric clip-pair oriented opposite to each other such that panels may be universally mated together along panel edges wherein panels can be flipped along panel midlines or rotated about panel center axes and mated in any orientation as allowed by the panels' shape and size as long as the panels' edges are parallel and aligned at the panel midlines.

A sixth aspect of the present invention is a clip assembly wherein clips are mounted symmetrically about the panel midline in pairs, or in any even integer, and with each symmetric clip-pair oriented in the same way to each other such that panels may be universally mated together along panel edges and panels can be rotated about panel center axes and mated in any orientation as allowed by the panels' shape and size, provided that the panels' edges are parallel and aligned at the panel midlines.

A seventh aspect of the present invention is a clip assembly wherein clips can be mated by physically pressing or snapping the male and female features together.

An eighth aspect of the present invention is a clip assembly wherein a tool or lever may be inserted into slots at the base of the assembly and rotated so that the tool acts as a cam on the ramp features to pry open the beams of the female feature. When the beams of the female feature are pried open, individual clip assemblies are more easily mated. When the tool is released or rotated in the opposite sense and removed, the beams of the female feature once again are allowed to close.

An ninth aspect of the present invention is a clip assembly with an internal mechanical latching member to allow individual clips to be latched to one another and/or unlatched by shifting a lever.

A tenth aspect of the present invention is a clip assembly with an internal fastening feature wherein a bolt or rotational cam-style fastener allows individual clips to be secured to one another.

A eleventh aspect of the present invention is a method of using the clip assemblies of the invention to secure panels together for assembly of furniture or a structure such as a jungle gym, solar panel frame or truss, office cubicle or shelter.

These aspects of the invention, as well as others described herein, can be achieved by using the methods, articles of manufacture and compositions of matter described herein. To gain a full appreciation of the scope of the present invention, it will be further recognized that various aspects of the present invention can be combined to make desirable embodiments of the invention.

I Clip Assembly with Male And Female Features on Planes Symmetric Out the Body Clip

Generally the present invention relates to a multiuse clip assembly wherein each clip includes both a male feature (1) and female feature (2). The clips can be used to secure panels or objects to one another for which the unique characteristics of the invention applies. Generally the invention is made of a thermoplastic material, though any other material or combination of materials may be used providing the material(s) possess the properties for the invention to work as described herein. When made from thermoplastic material, the invention can be manufactured in an injection molding process, though any other manufacturing processes may be used as applicable to the material being used.

Conventional fasteners are designed with mating features oriented along a common axis (as in a screw and nut or threads). The present invention employs a unique arrangement such that a clip body includes both a male feature (1) and a female feature (2) wherein the male and female mating features are located on two opposing planes symmetric about the clip body, whose plane of symmetry (21) is defined by a plane passing through the middle of the of the clip body. These defined symmetric planes form the legs of an isosceles triangle (22) whose included angle may be any angle as required. Two additional planes (8) internal to the clip/fastener body on the female side form a load-bearing interface, wherein the planes form the legs of an isosceles triangle (23) whose base is formed by the plane locating the female feature. The included angle of the two internal planes is any angle as required.

II Clip Assembly with Snap Fit Male And Female Features on Orthonogal Planes

The present invention can include a multiuse “snapping” clip assembly. Some features of the invention are the male (1) and female clip (2) features, one each of which are located on one of two orthogonal planes (3). The two orthogonal planes are themselves oriented at 45° (4) to the main body of the clip.

Here, the female feature (2) includes two flexible parallel beams (5) extruded from the main body of the clip, the ends upon which are located capture features with dual beveled edges, one outside (6) and one inside (7). Between the two parallel beams (5) and formed by the central rib of the clip body are two orthogonal surfaces (8), one of which is oriented normal and the other parallel to the body of the clip, both of which are at 45° to the female feature.

The male feature (1) includes a single extruded T-shaped beam (9) with beveled edges (10) on the top surface of the flange and flat faces or beveled edges (11) on in the inside of the flange. The ends of the T-shaped beam (9) are shaped such that two orthogonal planes are formed (12), one of which is oriented normal and the other parallel to the body of the clip, both of which are at 45° to the male feature (1), upon which is located one groove (13) on each plane.

Ramp features (14) may be located on both inside faces of each parallel beam (5) of the female feature (2), with a slot feature (15) located adjacent to each beam (5) in the walls of the clip body. Both of these features may be used together with a tool to facilitate locking and unlocking of the female feature (2) for either assembly or disassembly of two clips.

III Clip Assembly with Two Internal Planes That Form A Load-Bearing Surface

In a preferred embodiment of the invention, clips are located at 90° to each other and with the male and female clip features at 45° (4) to the panels. This is illustrated with a side view of a clip with the dashed horizontal line representing a panel edge (FIG. 3). Internal features (8) mate at 90° to the panels. This is illustrated with the mated pair views of the clips (FIG. 14, 15, 17).

A side view of a pair of clips is also depicted. (FIG. 10) The clips may be mated with one approaching from any direction within a 90° field of view (16) of the mating clip feature provided that the mid-planes of the clips remain coplanar.

IV Clip Assembly Used to Secure Panels Perpdenicular to Each Other

In a preferred embodiment of the invention, clips are located at 90° to each other with the male and female clip features at 45° to the panels. Internal features mate at 90° to the panels. This is illustrated by panels that are secured perpendicular to one another (FIG. 23) as opposed to panels that are parallel to one another (FIG. 22).

V Clip Assembly with Expandable Mating System

Conventional fasteners typically utilize two unique separate male and female parts to mate together one clip to another. This exhausts the mating locations after assembly of the two parts. In the present invention, two mated clips do not exhaust mating locations, but leave two more mating locations (19) for assembly of at least one more clip to the two previously mated clips. (FIG. 6, 8) Clips can be mounted symmetrically about the panel midline in pairs, or in any even integer, and with each symmetric clip-pair oriented in the same way to each other such that;

The system allows for infinite expandability of the panel structure given that the any panel added to the structure will further add additional mating sites, either along the same mating edge, or elsewhere in the panel structure.

VI Clip Assembly Wherein Clips A Mounted Symmetrically about the Panel Midline in Pairs

Panels may be universally mated together along panel edges as illustrated. (FIG. 19) This allows versatility to the use of the panel. Panels can be flipped along panel midlines or rotated about panel center axes and mate in any orientation as allowed by the panels' shape and size, provided that the panels' edges are parallel and aligned at the panel midlines.

Two previously mated panels allow for at least one more panel to universally mate as described above with the two previously mated panels, as illustrated (FIG. 20)

VII Joining or Separating Clips with Flexible Snap-Fit Features

“Snap-Fit” clips can be conducive to lightly loaded structures that are intended to be rearranged, expanded or frequently modified.

Two clips are mated together by inserting the male feature (1) of one clip into the female feature (2) of anther clip. The male feature (1) of one clip can be pushed into the female feature (2) of another clip with enough force so that the beveled top surface flange (10) of the male feature (1) acts as a cam on the outside beveled capture feature (6) of the female feature (2) so as to cause the beams (5) to flex open. The angles of the beveled edge (10) of the male feature (1) and the outside beveled edge (6) of the female capture feature may be varied by design to tailor the mating insertion force if applicable to suite the requirements of the intended end use of the invention. Once the clips are fully mated (FIG. 6) the two orthogonal rib surfaces (8) inside the female feature (2) mate with the two orthogonal surfaces (13) of the male feature (1) which forms the main load bearing interface, and the edges of the groove features further constrain the clips in shear loading applications. Because each clip includes one male (1) and one female (2) feature, one of each type of clip feature from each clip body will remain available (19) to assemble more clips after two clips have been mated.

The 45° arrangement (4) of the male and female features described above allows for two clips to be mated together such that the clips can be oriented either orthogonal (FIG. 6) or parallel (FIG. 8) to each other, depending on the intended use if the invention. Furthermore, the clips can be mated with one clip approaching from any direction within a 90° field of view (16) of the mating clip feature provided that the mid-planes of the clips remain coplanar. If the clips are mated such that the clip bodies are orthogonal to each other (FIG. 6), up to four clip bodies can be mated together in one location (FIG. 7) before exhausting all of the male and female features from all four clip bodies. If the clips are mated such the clip bodies are parallel (FIG. 8), an infinite chain of clips (FIG. 9) can be mated with at least one clip feature always left available to mate another clip.

The clips can be separated or “de-mated” by removing the male feature (1) from the female feature (2). Enough force can be applied in any direction within the 90° planar field-of-view (16) with a sense away from the clip features being de-mated so that the underside of the male flange (11) acts as a cam on the inside beveled capture features (7) of the female feature (2) so as to cause the beams (5) to flex open allowing the male feature (1) to be removed. The angle of the underside of the male flange (11) and the female capture feature bevel (7) can be varied by design to tailor the de-mating force if applicable to suit the requirements of the intended end use of the invention.

VIII Joining or Separating Clips with Flexible Snap-Fit Features with Use of A Tool

Snap fit clips can be used for structures with higher loading requirements that are intended to be less frequently rearranged, expanded or modified by varying the angle of the underside of the male flange (11) and the female capture feature bevel (7) such that a tool would be required to separate the clips after assembly.

Ramp features (14) may be located on both inside faces of each parallel beam (5) of the female feature (2), with a slot feature (15) located adjacent to each beam (5) in the walls of the clip body. Both of these features may be used together with a tool to facilitate locking and unlocking of the female feature (2) for either assembly or disassembly of two clips. A tool or lever can be inserted into the slots (15) and rotated so that the tool acts as a cam on the ramp features (14) to pry open the beams (5) of the female feature (2) (FIG. 11). When the tool is rotated in the opposite sense and removed, the beams (5) of the female feature (2) once again are allowed to close (FIG. 11). The ramp features (14) and slots features (15) may be omitted when not required for the intended end use of the invention, or in the case that a different tool is used to achieve the same result that does not require the use of the ramp (14) and/or slot (15) features.

The female feature (2) can be opened using a tool by the method described above before inserting the male feature (1), and reclosing the female feature (2) after the male feature (1) has been inserted by removing the tool as described above. Thus the flange of the male feature (1) is secured by the inside beveled capture features (7) of the female feature (2) acting on the underside of the flange (11) of the male feature (1).

To separate or “de-mate” the female feature (2) can be opened using a tool by the method described above before removing the male feature (1), and reclosing the female feature (2) after the male feature (1) has been removed by removing the tool as described above. The angle of the underside of the male flange (11) and the female capture feature bevel (7) can be varied by design to tailor the de-mating force if applicable to suit the requirements of the intended end use of the invention.

IX Method of Using Clip Assemblies to Secure Panels to Each Other

Two or more flanges (17), or any other features which may extrude from any part of the clip body, may be used to fasten or otherwise attach the invention to objects or assemblies for which the invention is being used. Optional spacer features (18) may be located on each side of the clip body which can act as locating features when the invention is fastened to a panel by way of a T-shaped slot (FIG. 12). The invention can be fastened or in any other way attached to objects or assemblies for which the invention is being used in any manner that suits the intended end use of the invention, or the invention can be manufactured as an integral part of the object or assembly for which it is being used.

When two panels are mated, one male and one female feature remain to add more panels. Pairs of clips are used on each panel edge. Each pair of clips on each edge are oriented opposite to each other. This allows panels to be flipped and still install.

Alternatively, panels may be secured using clips with the latching mechanism or fastening mechanism.

X Clip Assembly with Internal Latching Mechanism

As an alternative to snapping features, the clips can include a latching mechanism as illustrated (FIG. 13). The clips can have a built-in positive locking latch feature.

The use of latching clips may be preferred for use in semi-permanent structures which can still be easily taken apart, rearranged, modified and expanded.

XI Clip Assembly with Internal Fastening Mechanism

As an alternative to snapping or latching features, the clips can include a fastening mechanism as illustrated (FIG. 17). The clips can be fastened together with bolts or cams.

The use of fastening clips may be preferred for use in permanent or semi-permanent structures as well as highly loaded structures.

EXAMPLES Example 1: Development of Technology

A clip body (FIG. 1) includes the male feature (1). Two flexible parallel beams (5) are part of the female feature. The ends of the T-shaped beam are shaped such that two orthogonal planes are formed (12) on which are located a groove on each plane (13). Two or more flanges (17) on the base may be used to fasten or otherwise bind the clip to a panel or other object. Spacer features (18) may be located on each side of the clip body which can act as locating features when the invention is fastened to a panel by way of a T-shaped slot.

A different view of the clip body (FIG. 2) shows the female feature (2). Two flexible parallel beams (5) are part of the female feature. Two orthogonal surfaces (8) are formed between the two parallel beams. Ramp features (14) may be located on both inside faces of each parallel beam with a slot feature (15) located adjacent to each beam.

A side-view of a clip (FIG. 3) shows the two orthogonal planes (3) that are oriented at 45° to the main body of the clip (4) whose plane of symmetry (21) is defined by a plane passing through the middle of the of the clip body, and which form the legs of an isosceles triangle (22). Two additional planes (8) internal to the clip/fastener body on the female side form a load-bearing interface, wherein the planes form the legs of an isosceles triangle (23) whose base is formed by the plane locating the female feature. The ends of the T-shaped beam are shaped such that two orthogonal planes are formed (12). A slot feature (15) located adjacent to each beam in the walls of the clip body may be used together with a tool to facilitate locking and unlocking of the female feature for either assembly or disassembly of two clips.

An alternate view of a clip (FIG. 4) shows the extruded T-shaped beam (9), beveled edges (10) and the flat surfaces on the inside of the flange (11). A different angle (FIG. 5) shows the dual beveled edges outside (6), the dual beveled edges inside (7) and the ramp features on both inside faces of each parallel beam (14).

A perspective view of a clip (FIG. 6) illustrates clips that have been paired or mated. Because each clip has a male and a female feature, one of each type of clip feature (19) from each clip body will remain available to assemble more clips after two clips have been mated. Similarly, several (e.g. four) clips can be mated together (FIG. 7). If the clips are mated such the clip bodies are parallel, (FIG. 8, FIG. 9) an infinite chain of clips can be mated with at least one clip feature always left available to mate another clip.

A side view of a pair of clips (FIG. 10) depicts how they can be mated with one approaching from any direction within a 90° field of view (16) of the mating clip feature provided that the mid-planes of the clips remain coplanar.

A side view with dashed-lines representing internal aspects of a clip (FIG. 11) shows how a tool or lever can be used to flex the female features to assist in mating or de-mating clips.

A front view of a clip (FIG. 12) shows optional spacer features located on each side of the clip body which can act as locating features when the invention is fastened to a panel by way of a T-shaped slot. Individual clips can be secured to panels or other objects using an adhesive material such as glue. In the alternative, the clips can be attached with traditional hardware such as screws or bolts.

The latching mechanism is pictured with alternate views (FIG. 13). The male feature (1) and female feature (2) are present with latching features, orthogonal planes (3), and mounting feature (17). Two additional planes (8) form a load-bearing interface.

A side view of clips illustrates the mating and subsequent latching (FIG. 14) of clips. The male feature (1) and female feature (2) are present on two orthogonal planes (3). One of each type of clip feature (19) from each clip body will remain available to assemble more clips after two clips have been mated. Similarly a perspective view details a similar type of latching mechanism (FIG. 15). The male feature (1) and female feature (2) are present on two orthogonal planes (3). One of each type of clip feature (19) from each clip body will remain available to assemble more clips after two clips have been mated. A side view of a clip with dashed-lines for internal parts illustrates the mechanics of a type of latching system (FIG. 16). The male feature (1) and female feature (2) are present on two orthogonal planes (3).

One of each type of clip feature (19) from each clip body will remain available to assemble more clips after two clips have been mated A side view of a clip with dashed-lines for internal parts illustrates the mechanics of the fastening system (FIG. 18). The male feature (1) and female feature (2) are present on two orthogonal planes (3).

A perspective view and a close-up view demonstrating the use of paired clips to attach panels to form a modular-shaped structure (FIG. 19). Similarly the use of paired clips can be used to attach additional panels (FIG. 20).

Another use of the invention includes attaching solar panels to supports with mated clips (FIG. 21). A side view (20) of the solar panels illustrates details of the clip arrangements (FIG. 22, 23). The clips can be used to attach panels to form a shelter or structure (FIG. 24) without the hardware and efforts of traditional designs. The invention is also well suited to attach panels and other objects to form a playground set (FIG. 25).

This example provides for and establishes the early development of the technology and prototype clip assembly, methods of making same, and methods of using same.

Generally when made from thermoplastic material the invention is manufactured in an injection molding process, though any other manufacturing processes may be used as applicable to the material being used. For example, the clips and components can be made from metal or similar material.

Example 2: Using the Technology Basic Structure Example

This arrangement allows for versatility as panels or objects can be rotated and/or flipped in any axis as needed and still clip into existing structures. Panels or other objects can be added to one another without the use of tools or additional hardware.

Flat Panel Mounting Details

Panels can be prefabricated and include clips secured to edges as illustrated (FIG. 19). This allows the user to readily connect panels to one another to assemble a structure. With snapping clips, the user merely attaches panels by “snapping” the corresponding clips to one another. For greater durability, the latching or fastening clips may be used

The invention is particularly well suited to attaching solar panels to a roof, as illustrated (FIG. 21). The versatile nature of the clips allow panels to be easily attached parallel to one another or perpendicular to one another as illustrated (FIG. 22).

Basic Modular Structure

Panels can be prefabricated and include clips secured to edges. This allows the user to readily connect panels to one another to assemble a structure. With snapping clips, the user merely attaches panels by “snapping” the corresponding clips to one another. For greater durability, the latching or fastening clips may be used.

Panels are universal so that they can be rotated and/or flipped in any axis as needed and still clip into existing structures. Further, panels may be added to any structure at any time ad infinitum without modification to either the existing structure or the added panels.

The system is scalable and may be used for table-sized systems to large buildings.

Panels may be shipped flat so that space is saved. For example, if used for assembling emergency disaster shelters, many shelters can be shipped on a single truck.

The panel system allows structures to be quickly assembled on site in any size, to suit the required use. Further, panels are universal and can be used to modify or expand structures as needed.

Basic Shelter Structure

Large wall panels can be prefabricated and include clips secured to edges. They are packed and shipped to the retailer and/or the user, and many flat panels can be efficiently transported on the trailer of a truck

The panel system allows the consumer to quickly assemble any sized shelter or storage structure to fit his/her needs as illustrated (FIG. 24). Because the panels are universal, they can be used to modify or expand any structure as needed or desired. The system is also cost effective for the consumer because it can be easily modified and infinitely expanded and modified.

Playground or Jungle Gym Structure

As described, panels can be prefabricated and include clips secured to edges so that they are easily packed and shipped.

The panel system allows the consumer to quickly assemble any sized structure to fit his/her needs as illustrated (FIG. 25). Because the panels are universal, they can be used to modify or expand any structure as needed or desired. This allows the user to modify or expand the playground/jungle gym according to his/her desires.

This example provides for and establishes the early development of the technology and prototype, methods of making same, and methods of using same.
